Personal Game Idea

So I started on making concepts for a personal game. This is for my Game Development class, and we're making platformers for our personal projects. My idea revolves around my character, Deanster. Basically he controls the weather with his emotions. I'm still working on the story portion of the game, but I have some of the basic gameplay elements down.

Some concepts of The Deanster and his different abilities.

And these are some ideas of how the secondary characters might look.

Some ideas for the antagonists of the game: the "White Cloaks."
